i had ordered one cheese burst farmhouse pizza and a garlic breadstick on 7th may 2023 order no.182, total was rupees 672. the order got delivered close to 1 hour. when the delivery guy came he said even after "half hour guarantee or free" all i can get was 300 rupee off on my order and that too i have to pay full and would get 300 in my dominos wallet. so i paid 672 rs and waited for my refund, from 7th may 2023 till 20th may 2023 it has been more than 10 days (as told by store that it would take 10 days for refund) and still i have not got any refund. i have contacted customer care many times and every time all i get is a ticket no. 5740213, 5658495, 5725993. even after contacting these many numbers of times my problem has not been resolved. whenever store contacts me they are very rude while delivering any message and are unable to solve my any problem regarding the issue. please would you help in getting my 300 refund in dominos wallet and please dont try to contact me from store as the people there are untrained and not at all polite to talk to.
